Under certain conditions a dummy STA entry could be left in the station list. This causes subsequent connection attempts to fail. Logs look like this: authenticate with 00:23:69:aa:dd:7b (try 1) authenticated failed to insert Dummy STA entry for the AP (error -17) deauthenticating from 00:23:69:aa:dd:7b by local choice (reason=2) Fix this by making sure to remove the dummy STA on deauth.
